Yes, you can reschedule multiple flights on American Airlines, but it depends on how your flights were booked. If you purchased a multi-segment itinerary or connecting flights on one reservation, it’s generally easier to change all flights at once by contacting American Airlines.

To reschedule multiple flights, call American Airlines customer service at ☎‪+1(833) 613-4585‬. Have your full itinerary or confirmation number handy. The representative will review your flights and available alternatives. If the flights are on one ticket, changes will typically apply to the entire itinerary.

You can also attempt to make changes through the American Airlines website or app if your flights are linked. However, changing multiple flights might require an agent’s assistance to handle fare differences or waive change fees if applicable.

If you have separate reservations, rescheduling flights individually might be necessary. In this case, calling ☎‪+1(833) 613-4585‬ is still advisable to coordinate timing and minimize potential issues with connections.

Note that change fees and fare differences apply unless you have a flexible ticket or travel credit. It’s important to reschedule as soon as possible to maximize available options.

For group bookings or complex itineraries, the airline’s customer service at ☎‪+1(833) 613-4585‬ can offer the best support and possibly special handling.

Overall, American Airlines allows rescheduling multiple flights, but contacting them directly ensures your changes are properly coordinated.
